Hi everyone,<\/p>\n

I have hyperelastic simulation<\/p>\n

I have head soil nail cover with balloon, it is inside the soil. Then I put pressure around the inner surface of balloon. I need to get balloon inflating about 2 cm.<\/p>\n

I try to put pressure gradually, right now I reach 1,6 mm with pressure 136 kpa (it has already needed 2 days to be solved)<\/p>\n

to get 2 cm target, it will be about 1000 kPa. but i got element distortion on balloon element and there is newton rapshon in soil element.<\/p>\n

I have tried refine the mesh again and again but there is limited capacity of my computer. is there anything i could do to reach 1000 kPa.<\/p>\n

Thank you<\/p>\n

this is the model before failure<\/p>\n
